Grayson and Laurie in “Rhino Skin”

Smith wasn't attracted to you because he thought you were couth.

Grayson, that is a word that only women are allowed to use when they're really angry with another woman.

Couth. You know, the opposite of uncouth.

Right, because if I didn't know what couth meant putting an un in front of it makes it perfectly clear. Who's dumb now?

Obviously I am.
